-3x+y = 14 2x-5y= -18

cari x sama y nya kah?

-3x+y = 14
2x-5y = -18

-6x+2y = 28
6x-15y = -54

6x-2y = -28
6x-15y = -54
_________-
13 y = 26
y = 2

substitusi kan ke salah satu persamaan

-3x + y = 14
-3x + 2 = 14
-3x = 12
x = -4
HP = {(-4,2)}

-3x+y=14 (×2)
2x-5y=-18 (×3)

-6x+2y=28
6x-15y=-54
_________+
-13y=-26
y=-26/-13
y=2

-3x+y=14
-3x+2=14
-3x=14-2
-3x=12
x=12/-3
x=-4
maaf kalau salah
